Finding Max/Min Values With Multiple Occurrences
We can also find the indices of all occurrences of the max/min value of a matrix in a similar way. See the following code for understanding the same.
Example 4:
Matlab
% Finding Max/Min Values With Multiple Occurrencesmatrix = [1 2 3; 1 23 4; 2 23 5]%Getting valuesmin_val = min(min(matrix));max_val = max(max(matrix));% Getting indices as vectors% All of minx, miny, maxx, maxy are vectors[minx,miny] = find(matrix==min_val);[maxx,maxy] = find(matrix==max_val);% Displaying the valuesfprintf("minimum index\n")disp([minx,miny])fprintf("maximum index\n")disp([maxx,maxy]) |
Output:
As can be seen, the minimum value 1 occurs at (1,1) and (2,1), and the maximum value 23 occurs at (2,2) and (3,2) indices. The same results are given by the above code.
Find Indices of Maximum and Minimum Value of Matrix in MATLAB
Matrices in MATLAB are 2-dimensional arrays that store mostly numeric data at different indices. Now, to find the indices of maximum and minimum values of a given matrix, MATLAB does not provide any direct functionality however, we can do the same by using two other functionalities. Firstly, we will find the maximum or minimum value of a given matrix and then, we will find the indices of those two values. In this scenario, MATLAB does offer simple functions to perform the former tasks. In this article, we shall see how to do the same for a magic square.
